Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an auxiliary fixation device for foot and ankle injuries. Background Art

[0002] The foot and ankle are important parts of the human body that bear weight and move. Ankle and calf fractures are common in orthopedic trauma. After such fractures occur, the injured part usually needs to be fixed with a brace or plaster before surgery. This measure is intended to stabilize the fracture ends and avoid further damage. It also creates favorable conditions for subsequent surgical treatment, such as preventing the fracture site from being dislocated and aggravated due to accidental activities while waiting for surgery.

[0003] However, there is a serious potential risk during the use of braces or plaster fixation before surgery, namely the formation of deep vein thrombosis. After the limbs are fixed, the active contraction function of the muscles is limited, and the normal muscle pump function cannot be effectively exerted, resulting in a significant slowdown in the venous blood return rate. At the same time, the body's hypercoagulable state caused by trauma and vascular endothelial damage and other factors work together to make blood easily accumulate and form thrombi in the deep veins of the lower limbs. At the same time, after the patient undergoes surgical treatment, he enters a long rehabilitation stage. Wearing a brace for lower limb weight-bearing functional exercise is a key link in the recovery process. However, traditional braces expose obvious defects in this process, that is, they cannot accurately control the patient's weight load. At different times after surgery, the degree of fracture healing of patients is different, and the amount of weight-bearing stimulation required is also different. At present, clinical practice mainly relies on the doctor's experience guidance and the patient's self-perception to carry out weight-bearing exercise. There is a lack of precise quantitative standards and real-time monitoring methods. It is difficult to ensure the scientificity and effectiveness of weight-bearing exercise, which greatly affects the patient's rehabilitation effect and quality of life. Summary of the invention
